TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.
Westinghouse Electric Company is the world's leading supplier of new nuclear plants, products and technologies. We provide our utility customers around the world with the most reliable, dependable nuclear power plants, nuclear fuel, plant automation and operating plant products and services. Our AP1000© reactor is the only operating Generation III+ reactor with fully passive safety systems, modular construction design and has the smallest footprint per MWe on the market. Our AP300™ SMR, which launched this year, is single-loop pressurized water reactor that is based on the proven, licensed AP1000 technology. In addition to these advanced LWRs, Westinghouse is also developing non-traditional nuclear technologies in order to meet the needs of diverse and evolving global markets. Specifically, the Westinghouse eVinci™ microreactor is designed to provide approximately 5 megawatts of electricity / 15 megawatts of thermal power 24 hours a day, 7 days a week for eight-plus years without refueling. The Westinghouse Lead-cooled Fast Reactor is a utility-scale (450 MWe) Generation IV plant designed to best complement advanced passive LWRs through enhanced application versatility that combines flexible cost-competitive electricity, high-temperature heat and the capability to support a closed fuel cycle. Our comprehensive and innovative technology portfolio creates a blueprint for a carbon-free ecosystem that serves communities large and small with reliable, cost-effective electricity, district and process heat, and water desalination.
